' To all whom it may concern.-

Be it known that I, GEORGE M. RIDENOUR, a citizen of the United States, residing at Terra Alta, in the county of Preston and Stateof West Virginia, have invented certain new and useful Improvements in Heating-Drums; and I do hereby declare "the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates toc'ertain improvements in heating-drums.

The object of the invention is to provide an exceedingly simple, durable, and effective heatin'gdrum which can be manufactured easily and at a small cost'and placed on the market at a reasonable price, and which is so constructed as to be easily taken apart'for cleaning and for the removal of sootor other accumulation of deposits, and which will not materially retard or cut off the proper draft [of the stove, and yet will effectually utilize the waste heat of the products of combustion passing off from the stove and will deflect the heat to the outer shell or radiating-surface of the drum.

A further obj eat of the invention is to provide certain improvements in construction and arrangements of parts whereby an improved and highly efficient heating-drum will be produced.

The invention consists in certain novel features in construction and in combinations and arrangements of parts, as more fully and particularly pointed out and described hereinafter.

Referring to the accompanying drawings, Figure 1 isa side elevation of the heatingdrum, dotted lines showing the internal deflectors and partitions. Fig. 2 is a central vertical section. Fig. 3 is a horizontal sectional view through the cover or removable upper end. Fig. 4 is a view corresponding to that shown in Fig. 2 with the cover reversed to permit a direct draft or passage through the drum. Fig. 5 is a detail perspective of the internal removable partition or deflectors.

In the drawings, a is the shell or outer casing of the drum, usuallyprovided with suitable bottom legs or supports a, of any suitshell is closed by the removable cover or topb, which has the depending flange fitting around the upper end of the shell and usually moving down against the rib a, pressed in the metal of the shell. This shell is usually arranged vertically of a suitable length, and is preferably, although not necessarily, oval or elliptical in cross-section.

c is the inlet into one side of the bottom of the drum and to which the smoke-pipe from a stove is properly coupled, so that the smoke and products of combustion from the stove will pass directly into the drum.

d d are outlets from opposite sides or ends of the top b of the drum, and to either of 'which the ofitake-pipe is coupled. One of these outlets is always closed by any suitable removable device, such as a plug e, carrying a vase, receptacle, or other ornamention, and which removably fits and closes either one of the outlets, according to the adjustment of the cover or top.

A removable partition is vertically arranged within the drum and centrally divides the sameinto two about equal vertical chambers, and this partition is made up of two like deflectors f f, shaped to throw the heat and products of combustion outwardly against the inner surface of the shell of the drum as they pass against, around, and between the two deflectors. Each deflector .is formed of a curved vertically arranged plate of sheet metalthat is, each deflector is curved horizontally to form a segment of a circle 'or into a concavo-convex shapeand the two deflectors are curved in opposite directions, and each in vertical length is considerably more than one-half the internal vertical length of the drum. The lower deflector f rests at its lower edge on the bottom of the drum with its vertical edges engaging the opposite side walls and with the deflector from said vertical edges convexing outwardly toward the side or chamber of the drum where the products of combustion enter. The upper deflector f extends down from the top of the drum with its vertical edges engaging the sides of the drum,.and to a point considerably below the upper end of the lower deflector, and being curved in the opposite direction to the lower deflector the central portions of the convexed faces of the upper and lower ends of the deflectors meet and are riveted together at f", leaving the vertical passages on each side of said secured portions of the deflectors and between the oppositely-curving sides of the deflectors. The products of combustion enter the lower end of one vertical chamber formed by the partition composed of the two deflectors and flow up to the top of said chamber and are deflected downwardly and pass down through the two vertical passages between the separated overlapping portions of the deflectors and up around the lower edge of the upper deflector into the opposite vertical chamber in the drum. From the last-mentioned Vertical chamber the products of combustion pass up through the top opening 9, formed by a horizontal partition h, in the cover and a distance below the top plate of the cover, and which forms a horizontal passage between said partition and top plate closed except at the opening g at one end of the passage and the outlet-pipe at the opposite end of the passage. The outlet d, which is normally employed, extends from the end of the cover and said passage opposite the opening 9, while the outlet d, which is normally closed, is immediately over said openmg g.

In summer when it is not desired to utilize the heat of the products of combustion the cover is reversed so that the opening g is immediately over the inlet in the bottom of the drum and the closure 6 is removed from outlet cl and placed on outlet (1, so that the products of combustion flow directly through the drum in a vertical path without being retarded or having the direction of the draft changed.

The entire device can be easily made from sheet metal without difficult joints or a plurality of pipes, and I also wish it understood that I do not limit myself specifically to the curved deflectors, as they can be otherwise arranged, although I prefer the oppositelycurved deflectors, which throw the heat against the inner surface of the drum and form the two vertical intermediate passages on opposite sides of the securing-point between the deflectors and against or along the inner surface of the wall of the drum.

Material advantages are attained by having the interior of the drum open or free from obstructions, except for the vertical partition, as the removable top or cover 'can be lifted off and the partition removed, and thus the entire interior of the drum be rendered free and open for removal of soot and dirt. This is a feature of great importance in those 10- calities where soft and dirty coal is employed.

It is also evident that various changes might be made in the form, constructions, and arrangements of the parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the exact constructions disclosed and described.

That I claim is- 1. A heating-drum having a partition dividing the interior of the drum into two longitudinal communicating compartments, and a cover provided with a partition forming a horizontal passage with a smoke-outlet at one end and at its opposite end opening directly into the end of one of said compartments, the opposite end of the other compartment having a smoke-inlet, substantially as described.

2. A heating-drum comprising a shell with a smoke-inlet, a removable and reversible cover provided with a partition forming a horizontal passage at one end opening into the interior of the shell with a smoke-outlet at its opposite end and another smoke-outlet above said opening, and means for closing either of said openings, substantially as and for the purpose specified.

3. A heating-drum comprising a shell havin g two oppositely-curved deflectors arranged and supported therein to divide the shell into two longitudinal compartments,an outlet from one compartment and an inlet into the other compartment, said two deflectors overlapping at their adjoining ends and forming between their overlapping portions the intermediate passages from one compartment to the other, substantially as described.

4. A heating-drum comprising a shell with a removable cover, a vertical removable partition within the shell dividing the same into two longitudinal compartments, whereby the cover and partition can be removed to permit easy cleaning of the drum, said partition composed of two deflectors overlapping and secured together at their adjoining ends and formed to make an indirect passage between said overlapping ends from one compartment to the other, one compartment having a smoke-inlet and the other a smoke-outlet, substantially as described.

5. In a heating-drum, the combination of a shell having a bottom inlet, the oppositelycurved overlapping deflectors within the shell and secured together to form a partition and the two passages from one side of the partition to the other side, a removable reversible cover having two smoke-outlets, removable means to close either outlet and leave the other open, said cover having the horizontal partition forming the passage under said outlets and opening at one end into the interior of the shell, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
